I am looking at Administraton --> Timesheet Settings --> Entry Level Custom Fields --> A drop-down field we have created. We have deleted several items in the field, but they still stay in the list only with "(disabled)" behind the deleted items (items are not in fact deleted, just disabled). It is very messy and having the "(disabled)" does not help.

This is not something we plan to do currently. I would imagine some admins would want to be able to see the disabled options so we'd probably need to build some sort of filtering, rather than hiding them altogether. We'll leave this post open for other customers to add their votes, which will help us prioritize amongst other requests.
